Brief Summary

Introduction

H. reversa is one of the most common species of histioteuthids in the North Atlantic. Its range extends into the eastern South Atlantic. The length of the gladius in the largest recorded female is 183 mm (Voss, 1969). Like many histioteuthids, major morphological changes occur at sexual maturity. In this species the females become much more elongate and develop an additional array of photophores.
